{"version":"1.0","type":"rich","title":"Learn to draw smile with d3","description":"This example demonstrates basic SVG shape drawing with D3, showing circles, rectangles, lines, and paths arranged to form a playful smiley composition. The code uses plain D3 selections to append SVG elements inside a `<g>` container with a scale transform, while CSS classes like `.lines` style the stroke properties. A video tutorial link accompanies the code, which uses D3 v3 to manipulate SVG attributes directly without data binding or advanced visualization techniques.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/44066e09ea52405db90a0211fc7c9b71?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
